Great quality
Size: 7-8 Toddler, Color: Moo-moo Cow
These are so cute and comfortable. My 3 yo can put them on himself and it is so cute that they light up. Fit as expected and are great quality. Even the dog hasn’t been able to tear them apart. Would buy more styles!

Great brand
Size: 7-8 Toddler, Color: Moo-moo Cow
I usually order from their web site but they were out of stock so I decided to check Amazon and there they were. They are cute. The baby keeps them on his feet. They look warm because they are well cushioned. The quality is good and it makes a great gift because they light up.
